Application led December 3, 1920.' `Serial No. 427,933.\

rTo all whom t may concern.'

Be it known that I,"Ii`nnDnn1o TIMMER- MAN, a citizen of the United States of America, residingat'New York, borough of Manhattan, in the county of New .York and State of New York, have invented cee tain new and useful Improvements in Spring Compressors, of which the `following is a specilication.

This invention relates to valvey handling tools and more particularly to spring compressors. f

An object of the :invention is to produce improvements lin valve compressors to the end that this tool may be used for compressing a spring to facilitate the removal thereof from automobile 'engines so that the poppet valves of an internal combus tion motor may be expeditiously removed and replaced. p f

Among the `several objects yofmy invention I have in view the production of a spring compressor tool which clamps or compresses a spring and 'holds it in that position while the spring is removed and until the spring is replaced, whereupon the tool releases its hold to permit the spring to expand into its original position.

Referring to the accompanyingA drawingsk forming a part hereof, Figure 1 shows the spring compressing tool in side elevation with a spring `in position to be cornpressed. I

Figure 2 illustrates'afront view .of `the tool with the spring locked inthe tool and being in compressed position. i

Figure 3 shows a sectional view of the spring compressor as taken on the line 3 3 of Figure 2. i

Figure 1- illustrates a cross-sectional View taken on the line Ll-bof Figure 2. v

A spring compressor-tool constructed in accordance with the plans of my invention embodies a casing with a spring rseat or support on one end and a slide confined in the other end. i-Mtoggle mechanismis employed to move the slideup and downv to compress and release the spring. s

Referring now more in particular to the drawings for adescripticn of the parts of the invention,y ythere is shown a, casing 6 made round or partly cylindrical in form with one side left open to receive a coil springto be compressed. "I-hevcasing is` made with a flange or support 7 on oneend thereof byturning inwardly the end ofthe casing. The outer parallel Vedges of the casing are 'turned yinwardly to formguides S.

,A slot` is formed, vertically `in "the casing to admit and guide alpin or? stud used to transmit motion to later described. i

A slide 11 is made similar in form to the casing 6 except thatit is shorter and'slightly smaller insize to fit into the casingwith its outer parallel edges slideably conned in the compressor part, as

`the guides 8 so as to maintain`- the slide in proper position during its reciprocal `motion in the casing. The upper endoffthe slide is made with a flange 12v turned inwardly similar to the flange orsupport 7 in ade on theotlier end of the casino* 6.

A wheel, or-in` fact a crank, is gournaled .On a suitable bearing anchoredon fonel end of the casing 6 andthis crank preferably .comprises a socket-hub14L, integrally formed rwith spaced flanges 15. @ne lend ofaflink 16 is conii`nec'ljbet\veen the lianges 15 and connected thereto 'by 1a journal pin 17 The other end of this link is pivotally connected with a pin or stud 18 which is confined in the slot 9 and anchoredto thefslide 11.

'A key orhand toolf20 hasa square or hexagonal ball-shapedend" 21 and may i. be inserted into the'socket-hub ll-,wherebythez wheel or crank 14-15 isrotated `'lhekey 2O is made with the ball-shaped` endf21so mechanic moves the slide to its uppermost position and slips the casing overthe coil `springuntilithe spring is 'confined in the casing as shown in Figure 1 lwith the flanges 7 and 12 engaging coils of the spring. The key 20 is their turned which draws the slide 11 toward the .liange 7, ythus compressing `that portion of the coil spring confined between the two flanges 7 and 12. The crank 15 isrotated somewhatniore than 180; degrees Lso that thek point of link connection 17 passes theline ofcenter fof action in ,the

ytogglemechanism;whereby the slide 11 is locked jin its lowerinost'position and.k will not permit the spring to expand when the key 2O is removed from the socket of the crank.

lith this character ot spring compressor, it is possible to easily remove a valve spring from an internal combustion motor and leave it in the tool until the springis replaced, whereupon the key is again used to rotate the crank or wheel 15 until the compression of the spring acts to open up the device to permit the spring to expand to its original set position.

An additional feature of this tool resides in the ability of the casing 6 to hold the compressed spring in position to prevent it from bulging out from its compressed center which so often happens with many other types of devices. The spring is held in straight and aligned position within the casing during the time that it is under compression.

Having thus described the construction and operation of a spring compressor con.- stituting an embodiment of my invention, what l desire to claim and secure by Letters Patent is:

1. A spring handling and compressor tool comprising a pair of spring grip members movable one in relation to the other, a link having one endpivotally attached to 'one of the aforesaid members, and a rotatable device journalled on the other member and having pivotal connection with the other end of the aforesaid link, the said link being curved so as to swing around the axis of the rotatable device with the middle portion thereof engaging the rotatable device so as to effect a locked position to hold a spring compressed, and handle means related with the rotatable device to operate the tool. f 2. A spring compressor comprising a iframe, a slide confined and movable in the frame, a link connected with the slide, a rotatable member connected with the link to actuate the slide, said rotatable member provided` with a socket, and a handle arranged to engage the socket to operate the rotatable member.

3. A spring compressor tool comprising a iframe to encompass and hold a spring in alignment while being compressed,` a slide movable in relation to the -frame and adapted to engage a spring to compress it, a device to move the slide, a handle carried by the compressor tool to operate the device, and the said handle having a universal connection established with the tool so that an opcrater may stand at a selected position 'of advantage and actuate the tool from any angular position.

4. A spring compressor tool comprising a frame to encompass and hold a spring in alignment while being compressed, a slide movable in relation to the frame and adapt- 'ed to engage and compress a spring, said Lacasse tool being provided with a detachable handle so that the tool in use may first have its irame and slide set up against a valve spring in an engine, atter which the handle is in` serted to work the tool from any angle.

5. A spring compressor comprising a device constructed in the 'form of a casing to partly surround the coils of a spring to be compressed, a slide movably confined in the casing, a flange made on the casing and on the slide to engage and hold a spring, a rotatable member journalled on the frame, a curved toggle link connection established between the slide and rotatable member, and a handle carried by the rotatable member to move the curved link into a locked position whereby the slide is moved to compress the spring.
